' this specification, and to the letters of reference markedthereon. 1

My invention has for its'object the rapid transfer of cartridges from the magazine in which they are kept into the barrel to be dis charged, the prevention of any premature explosion by the forward movement of the hammer, the secure lockin g of the bolt in place against the cartridge when the latter is exploded, and the rapid loading and discharging of the arm by the simple movementof thelever toandfro.

To this end myinvention consists of aswinging lever operating a pivoted arm connected with and moving a carrier, said swinging lever being also connected with a link which carrice a pinion traveling in a stationary rack, which pinion moves the bolt to and fro to carry the cartridge from the carrier into the barrel.

The swinginglever is also connected with an arm pivoted to a lock used to secure a vertically-swinging breech-block up firmly against the bolt, the latter being adapted to move the breech-block in both directions. A projecting orpivoted piece on-the handle of the swinging lever, which strikes against part of the trigger, adapts thearm to be discharged rapidly by the simple movement of the swinging lever to and fro, all which-will he more fully here inafter described.

- i Figure I is a longitudinal vertical section of j-alportiouof the frame and barrel of a gun 'made according to my invention, showing the operating mechanism with the swinging lever thrown back and all the parts in position i when the hammer is down or thrown forward. Fig.II is a similar section, showing the swinging lever thrown forward, the carrier moved ,up to carry a cartridge into position. to be forcedinto the barrel, and the hammer thrown backatfull-cock. Fig. III is a side view of the so forward endofthe swinging lever. FiglVis a side view of the link which,connects the swinging lever with the traveling pinion.

In the drawings, A represents the frame of a magazine fire-arm, in which B is the barrel; 0, the magazine, made to contain any desired number of cartridges D, the carrier, operating in a vertical recess, 0, and provided with a recess, 0, (shown in dotted lines,)to receive a. cartridge.

G is an arm pivoted in the frame at o, the forward end of which arm engages with the carrier D, and by which the latter is moved,

and the rear end of said arm is two shoulders, c and c.

H is a swinging lever, pivoted also at o, and whose forward end is provided with a pin. or

provided with projectiomi, asshown in Fig. III, and to which is also pivoted at o a spring pawl or latch, h, ar d the rear end of this swinging lever g forms the trigger-guard, and also the handle by which it is operated, to which handle is pivoted a piece, t, the use of which will be more fully hereinafter described. The link I (shown separatelyin Fig. IV) is pivoted also at o, and is provided with an elongated hole, i",

through which, when the parts are in place, the projection 'ion the forward end of thelever; H protrudes,'so that the latter may have a lit tle movement without moving the link'and pinion, as will be more fully explained. The

forwardend of the link is pivoted to the piece F, in which is held a pinion, f, traveling to and fro in the stationary rack f", and a belt, a, is arranged to move to and fro in theframe, being actuated by the traveling pinionf, whoseteeth engagewith similar teeth on the lower side of the bolt a. vThis bolt isfalso provided {with projections or teeth a at its rear end, which,

when the bolt is moved forward, engage with similar teeth, e, onthe breech-block E, pivot-- ed at e, which block, when the bolt is moved forward, bears uplagainst the, rear end of the bolt to hold. it' firm. f

. The arm- L is. pivoted its end to the projection or. pin a onf the forward endof the lever Land-which projects ,through the linkI,aijd therear endof the arm L .is' piv- Qifld 9 a 0 "N, swi i'g l pmi e h m erpivotwi, the upper'eiid of the lock being in a position heneatlrthe block '13 to hold it firm venient manner in the frame.

A projection, s, is made on the rear side of the trigger g, so that when desired the trip t,

pivoted to the handle of the lever H, may be thrown open, as shown in Fig. 11, and when the lever is brought up into the position shown in Fig. I the trip will strike against the projection 8 and release the hammer from its position at full-cock.

The lower end of the pawl his held out bya spring'placed inside, so that as the lever H is moved up the lower end of the pawl willstrike against the shoulders of the frame, as hereinafter further explained.

Th'coperation of myinvention is as follows: Theparts of the gun bein gin the position shown in Fig. I, and the magazine 0 being charged with cartridges, one of the latter is thrown back by the magazine-spring into the recess 0 in the carrierD. TheleverHbeingmoveddownward and forward, the projection 0', arm L, and lock N are moved back until the lock is out from beneath the block E, andduring this movement the lower end of the pawl h, which thus far has rested upon the upper part of the shoulder a: and served as a latch to hold the lever H up in place, is pressed in as it passes down until it has passed below the shoulder, when its spring forces the lower end out again until theupper end passes to a position beneath the lower end of the link I, as shown clearly in Fig. II. The

. projection 11 in the forward endof the lever 11 takes a bearing against thelinkI in the lower end of the hole 1', and as the long arm of the lever still moves down and forward the link I and pinion f are moved back, which moves t or the extreme forward end of the arm 11' back the. bolt a, the latter moving twice as fast and asfar as the pinion; The lock N having at this time moved back from beneath the block E, as the bolt a startsback it moves quickly the 1 block E into the .positionshown in-Fig. II by means of the teeth a". Asthe lock N startsto move back it impinges against the hammer K, and moves that back also, and the hammer and block E/now being entirely out of the way, the bolt,.as the movement of the lever H continues, is free to move back to the position shown in Fig. 11'. In this downward and forward movement of the lever H, when the pin reaches the shoulder c on the rear end of the arm G, the forward end of the latter and the carrier with which it engages are thrown up rward, bringing the recess 0 and cartridge therein directly behind and in line with the bore of the barrel B, when the forward movement of the lever His completed. In this position (shown in Fig. 11) the upper end of the pawl his beneath and against the lower end of the link I, and if the lever H now bemoved back, the link I, arm L, lock N, pinion f, and

thereby moved up into place against the rear end of the bolt, and when that is done the bolt has reached its foremost position, and the forward end of the bolt, having moved along the length of the recess 0 in the carrier, has forced the cartridge intothe barrel, and remains with its forward end against the head of the cartridge. As the backward and upward movement of the lever is continued the lower end of the pawl h rides against the shoulder at of the frame, and the upper end of the pawl is thereby forced rearward or out from beneath the lower end of the link I, so that the latter and the pinion cannot be forced farthersforward. As the pin 11 or forward end of the arm L reaches the shoulder c on the rear end of the arm G the forward end of the latter is thereby moved down, forcing down the carrier into its position to receive another cartridge, the pint meanwhile moving along the elongated hole 1" in the link, and the arm L and lock N being also drawn forward until the latter is in place beneath the block E. The hammer K being then in position of full-cock, the arm isdischarged by the trigger, as usual; or, if desirable, the pivoted trip t in the handle of the swinging lever H. may be opened out into the position shown in Fig. II, and if the handle be brought back and up against the frame the trip will strike against the projection s of the trigger, and thereby release the hammer, so that the arm having been placed in a desired position for the range it may be rapidly loaded swinging of the lever II to and fro. I

It will be perceived that as thus constructed it is impossible to let down'the hammer into a position to strike the fire-pin until the bolt a,

' the block E, and the lock N are moved entirely and discharged automatically by the simple forsecuring it in place at the rear end of the barrel have heretofore been so a'rrangedas to prevent the hammer from striking the fire-pin before the block and its look were 'up in'place, and thereby obviating the danger of premature explosion; and I do not claim that feature irrespective of my construction and arrangej ment of other mechanism connected with said look and block. y

Having thus described my invention, what I claim as new is-- 1 In afir'e-arm, the-combination of the lever B, the spring-pawl h, pivoted thereto, the link I, pinion f, and stationary rack f", as a means of'moving the bolt a to and fro in loading the arm and ejecting the shell, substantially as described. 2. The combination,in afire-arm,ofthe lever 9&5300 3 H, with its spring-pawl h, and the arm L, as a H, with its spring-pawl h, the link I, pinion f,

means of moving the brace into and from its place beneath the block, substantially as set forth.

3. In a fire-arm, the combination of the bolt a, the block E, and the brace N, substantially asset forth.

4. In a fire-arm, the combination of the lever bolt a, the arm L, brace N, and block E, op- 10 erating substantially as set forth.
